Generac Power Systems OG 2697 manual Generator Installation, Before Installation, NFPA Standards

This exhaust system must be installed properly, in strict compliance with applicable codes and standards.

Keep hands, feet, clothing, etc., away from drive belts, fans and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating.

Adequate, unobstructed flow of cooling and ventilating air is critical to prevent buildup of explosive gases and to ensure correct generator operation. Do not alter the installation or permit even partial blockage of ventilation provisions, as this can seriously affect safe operation of the generator.

Keep the area around the generator clean and uncluttered. Remove any materials that could become hazardous.

When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.

Generator Installation

These generators are air-cooled, engine- driven generator sets designed to supply electric power that operates critical electrical loads during utility power failure. Your generator was factory-installed in a weather resistant, all metal enclosure and are intended for outdoor installation only.

Before Installation

The generator’s rated wattage/amperage capacity must be adequate to handle all electrical loads that the unit will power. The critical (essential) loads may need to be grouped together and wired into a separate “emergency” distribution panel.

Connecting this generator to an electrical system, normally supplied by an electric utility, shall be by means of a transfer switch,

to isolate the electrical system from the utility distribution system when the generator is operating. Failure to isolate the electrical system by these means will result in damage to the generator and may also result in injury or death to utility workers due to backfeed of electric energy.

If an open bottom is used, the engine-generator is to be installed over non-combustible materials and should be located such that combustible materials are not capable of accumulating under the generator set.

Only qualified, competent installation contractors or electricians thoroughly familiar with applicable codes, standards and regulations should install this standby electric power system. The installation must comply strictly with all codes, standards and regulations pertaining to the installation.

After the system has been installed, do nothing that might render the installation in non-compliance with such codes, standards and regulations.
